Twisted transport.write

Question

Is there any way to force self.transport.write(response) to write immediately to its connection so that the next call to self.transport.write(response) does not get buffere

Answer 1

Maybe You can register your protocol as a pull producer to the transport

self.transport.registerProducer(self, False)

and then create a write method in your protocol that has it's job buffering the data until the transport call your protocol resumeProducing method to fetch the data one by one.

def write(self, data):
    self._buffers.append(data)

def resumeProducing(self):
    data = self._buffers.pop()
    self.transport.write(data)
